You want to create a copy of an active ZFS file system named dbase. When listing the information
on the file system, the following information is displayed:
NAME USED AVAIL REFER MOUNTPOINT
files/dbase 24.5K 72.8G 24.5K /data/dbase
data/dbase@bckup_dbase 0 – 24.5K –
Rather than unmount the file system, back it up and transfer the data to a second file system, you
want to create a point in time snapshot of the current dbase file system and copy that snapshot.
Based on the information displayed above, which answer describes the steps necessary to
complete this process?
A.
zfs snapshot data/dbase@ bckup_dbase
zfs clone data/dbase@bckup_dbase data/clone_dbase
B.
fssnap -F ufs -o bs=/var/tmp /data/dbase /dev/fssnap/0
mount -r ro /dev/fssnap/0 /data/clone_dbase
zfs clone /data/dbase data/clone_dbase
C.
zfs clone data/dbase@bckup_dbase data/clone_dbase
D.
zfs clone data/dbase data/clone_dbase
